Sulfohalite is a rare sodium sulfate mineral containing chlorine, fluorine, sulfur, and sodium, and is highly sought after by mineral collectors at Searles Lake, California. It is known for forming small, often transparent to translucent, yellow-green octahedral or dodecahedral crystals, often appearing as two pyramids stacked base-to-base. 

Searles Lake, located east of Trona in San Bernardino County, California, is the type locality for sulfohalite, where it was first described by Hidden and MacKintosh in 1888. It is found within the evaporite sediments of the Searles Lake basin.  While sometimes found in abundance, it can be rare and hard to find in other years, making it a prized specimen during collection events. Usually colorless, gray, or greenish-yellow, often with a greenish-brown tint.  Typically occurs as yellow-greenish octahedral crystals.  Crystals are generally small (thumbnail or micro size).

This is a 45.4 gram lot of beautiful tumbled Lapis Lazuli from Afghanistan.  There are 5 pieces that range in size from approximately 21-33x12-19 mm.  This is the exact lot that you will receive.

Lapis lazuli is a vivid blue metamorphic rock and a gemstone that has been prized for its intense color and historical significance for thousands of years.  It's composed of lazurite (for the blue color), calcite, sodalite, and pyrite. It is the presence of pyrite that causes the gold-colored flecks or veins in the stone.  It has a moderate hardness, typically ranging from 5 to 5.5 on the Mohs scale.  High-quality lapis lazuli has been historically sourced from mines in Afghanistan; however, other deposits are found in countries such as Russia, Chile, Italy, and the United States.

Lapis lazuli is believed to promote self-awareness and mental clarity.

Oolites in the Great Salt Lake, Utah, are tiny, sand-sized, spherical or ovoid grains (0.15–1.5 mm) formed by calcium carbonate precipitating in concentric layers around a nucleus—often brine shrimp fecal pellets or mineral fragments—in shallow, wave-agitated water. These light brown grains, commonly found on Antelope Island and Stansbury Island, are modern examples of carbonate sedimentation.

This geological specimen found around Stansbury Island and other parts of the Great Salt Lake is an interesting addition to any mineral collection.

This is a rare and fantastic 2.4 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 19x14x11 mm.  Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites.

Libyan Desert Glass is found specifically in the Great Sand Sea of the Eastern Sahara, within a more localized area spanning parts of western Egypt and eastern Libya.  Characterized by its yellow to greenish-yellow color, it lacks the aerodynamic shapes of tektites and often appears as irregularly shaped pieces. It is almost pure silica (around 98%) with very few impurities. Throughout history, it has been regarded as a mystical and powerful material, sometimes used in talismans and amulets.

This piece displays extremely well and is a quality translucent specimen. It has an aesthetic shape with a beautiful wind eroded body from the years spent in the Desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Pseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another.  The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.

The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.

This specimen is remarkable for its relatively sharp and bladed marcasite crystal form.  It is in excellent condition.

This is a rare 7.63-gram Impactite end cut specimen from the impact structure located near the village of Karlinskoye in the Ulyanovsk Oblast of Russia.  It is generally referred to as the Karla crater (Russian: Карлинский кратер). Its dimensions are 46x38x7 mm. 

The Karla crater, not to be confused with the Kara crater, is situated in the Ulyanovsk Oblast, near the village of Karlinskoye, not far from the city of Ulyanovsk. It is a confirmed meteorite impact structure with a diameter of approximately 10 kilometers (6.2 miles) with the age of the impact is estimated to be around 5 ± 1 million years old, placing it in the Pliocene epoch. The crater is considered exposed at the surface, and it features a complex structure with a central uplift composed of Paleozoic sediments and Archean crystalline basement rock, surrounded by a collapsed disruption cavity filled with breccia and lake deposits.

Take a closer look at a piece of history with this remarkable impactite. A highly unique addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a rare 21.69-gram Kamensk Crater Impactite end cut specimen from the impact crater located 10 to 15 kilometres (6.2 to 9.3 mi) to the north of Kamensk-Shakhtinsky town in Rostov Oblast, Russia. Its dimensions are 57x43x12 mm. 

Kamensk crater is 25 km (16 mi) in diameter and the age is estimated to be 49.0 ± 0.2 million years old (Eocene). The crater is not exposed at the surface.  It may have formed at the same time as the smaller and nearby Gusev crater. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection pieces you'll ever own.

The Gold Hill Wash Prospect, part of the Clifton-Gold Hill Mining District, is known for its rich mineral resources, including jarosite. This mineral is part of the larger group of minerals found in the area, which also includes limonite.

The Gold Hill Mine, operated by the Western Utah Copper Company in the early 20th century, was significant for its arsenic deposits, although it closed after World War I. The mine's portals and shafts have since been sealed by the state of Utah.

This specimen from the Gold Hill Mine is a matrix covered with minute jarosite crystals.  This specimen is an interesting addition to any mineral collection.

Name: Jarosite
Specimen Size:  Miniature-Sized
Dimensions:  53x49x33 mm / 2.1x1.9x1.3 inches
Weight:  64.91 Grams / 2.3 ounces
Origin: Mined in Gold Hill Mine, Gold Hill, Gold Hill Mining District (Clifton Mining District), Tooele County, Utah, USA

The NWA 267 meteorite fragment offered here is in as found condition.  It weighs 6.03 grams, with dimensions of 24x19x14mm.  The meteorite will come with two specimen description cards including a signed "The Mark Bostick Collection" card.

This meteorite was once a pile of weathered unclassified meteorite fragments brought to the 2000 Denver show by a Moroccan fossil dealer. These fragments, 73.9 kg. worth, where purchased by Canadian meteorite dealer Dean Bessey, who was told the following on the meteorites: "A nomad found an area with a lot of unusual strange stones near the Morocco/Algeria border. He brought one to a fossil dealer and asked: "I hear that you will pay money for stones like this". After shaking his head in disbelief at a positive response, the nomad gathered up all his camels, wives and children and brought them into the desert to search over his personal strewn field." Or at least that is how the story goes.

Many thousands of stones, 73.9 kilograms, were recovered, most of these fragments under 20 grams. Then 356 grams and a thin section of the meteorite was donated to the Vernadaky Institute of Geochemistry and Analytical Chemistry, part of the Russian Academy of Sciences, Moscow, where it was classified by M. Ivanova. This meteorite, an ordinary stone chondrite, H4 class has a Shock Rating of 2 and a Weathering Grade of 2-3 and the classification information was published in Meteoritical Bulletin 85.

While the stone did not get a heavy weathering grade, very few specimens show any crust. This meteorite is believed to have come from the Hebe class asteroids. I've included an informational photo of a NWA 267 Meteorite thin section which are used in earth geology, and in meteorites to identify the minerals in them. The photo shows a large imperfect elongated chondrule. Chondrules are unique features to meteorites. The chondrule shown is composed of mostly pyroxene and the bright colored minerals scattered throughout the thin section is mostly olivine.

One of the fun facts is that the NWA 267 was also the first meteorite ever minted onto a real legal tender coin. The National Bank of Liberia made 999 of these $10.00 Silver coins in 2004. The meteorite used in the coin, was supplied by Mark Bostick himself and his name and signature came on the certificate with the coin. The provided images of the coin shows a nomad on a camel on the obverse. A meteorite is falling through the star filled sky in the background. Reverse of coin has a seal of the Liberia Government and notes its value. We include 2 specimen cards but unfortunately the thin section and coin used in the ad are NOT included!

This is an incredible specimen of the Zag meteorite that fell in Western Sahara in August 1998. This rare and highly collectable H3-6 chondrite (S3 W0/1) is characterized by its beautiful fusion crust and is 1 of only 82 approved meteorites classified as such. The total weight is registered at 175 Kilograms and this nice piece is 1.1 grams with dimensions of 20x8x4 mm.

Zag made headlines around the world as the second meteorite to contain liquid water. Purple salt crystals have been found by scientists in Zag and liquid water is in bubbles in some of these crystals! Zag has been in almost every newspaper and even on CNN.

This piece displays very well showing some fusion crust. Would make an amazing addition to any collection. Comes with a Jensen Meteorites and a Canagem Collection Specimen card.
